The ABCs of Plasma Coating

The ABCs of Plasma Coating

  • Plasma coating is the application of a Nano-coating material onto a surface of a substrate via a plasma gas.
  • Plasma technology is based on a simple physical principle.  Matter changes its state when energy is supplied to it. Solids become liquid. Liquids become gas. If additional energy is then fed into a gas by means of electrical discharge it eventually ionizes and goes into the energy-rich plasma state.
  • The Plasma created can be used for applying Nano-coatings. The Nano-coating material is injected into the plasma gas via a jet nozzle. The plasma excites the coating material and this increases the coating materials reactivity. The plasma coating is then applied to the surface.
  • Due to the excited nature of the coating material in the plasma, the Nano-coating coverage is optimized and the bonding to the surface is improved.
  • The types of Nano-coatings applied can be hydrophobic (water repellent) and hydrophilic (water absorbent). This means you can change the wetting energy of the surface.
  • The choice of coating type will depend on your requirements. The plasma coating process can be used to coat different materials like metals, glass, ceramics and plastics.
